BICYCLE-SEAT.

provide in a manner as hereinafter set forth Specification of Letters Patent.

Application filed December 20, 1909.

and claimed what may be termed a childs I bicycle scat adapted to be detachah'ly secured to the bicycle frame forwardly of the saddle, whereby a bicycle can be utilized for carrying a child forwardly of the rider and without any inconvenience to the rider.

A further object of the invention is to pro vide a childs bicycle seat in a manner as hereinafter set forth and claimed which is adapted for use in connection with varying sizes of bicycle. frames without the employing of additional hold-fast devices for se-' curing the seat in position.

Further objects of the inve'utitm are to provide a ,childs bicyclcseat which shall be simple in its construction, strong, durable, readily secured to and removed from the bicycle frame, not interfering with the rider of the bicycle, automatically adjustable so as to adapt itself for use in connection with the varying sized bicycle frames, and inexpensive to manufacture.

\Vith the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as l'icreinafter more specifically described and illustrated in the accon'ipanying drawings, wherein. is shown the preferred embodimentof the invention, but it is to be understood that changes, variations and modifications 'an be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views: l igure 1 is a side elcvat ion of a portion of a bicycle frame showing the adaptation therewith of a.

childs seat in accordance with this invention. Fig. 2 is an inverted plan of the seat. with the. parts in an inoperative position. Fig. I) is a cross-section of the seat, looking in the direction toward the steering head of the bicycle. Fi 4 is a detail perspective Serial No. 534,232.

of the adjustable spring-controlled seat clamping device, and, Fig. 5 is a detail perspective of the abutment.

Referring to the drawings by reference characters, 1 denotes the steering head of a frame, 2 the cross bar which connected to the head .1 and to the saddle post (not shown) and 3 the handle bars. The foregoing elements may be of any suitable construction. i i

A child's bicycle seat in accordance with this invention comprises a base plate 4 which is preferably constructed of metallic material and provided with a continuous rim 5. the. contour of the base 4 being somewhat arch-shaped. .\lounted upon the base r and closed by the rim 5 is a cushion (3 of a contour similar "to that of the base and which projects above the rim The base 4 at its forward end has depending therefrom a pair of' forwardly inclined brackets 7 which are. adapted to engage the sides of the steering head, these. brackets snugly engage the steering head at. their lower portions and at their upper ends are olf-set as at S. The oll-sct= portions H of the brackets 7 abut against the lower face of the. base4 and are secured to the base through the medium of the hold-fast devi es i). The lower portions of the bracket 7 are maintained in position through the medium of inclined brace members 10 which at their lower ends are secured by the hold-fast devices 11 to the bracket 7 and at their upper ends are connected by the l'iold-fast devices 12 to the base 4-. The seat when in position is mou nted upon the bar and. arranged in close proximity to the steering head 1, the bracket 7 engaging the steering head and the cushioned seat 6 projecting above the bandle bars 3 as clearly shown in Fig. 1.

Secured to and depending from the lower face of the base 4 is an angle-shaped abutment which is adapted to bear against the bar 2 and the said angle-shaped abutment consists of a base 13 terminating at one end in a right-angularly-disposed grooved extension 14, the latter terminating in an inclined brace 15. The brace 15 is secured. to the base 13 by the hold-fast. device it), the latter also connects the base 13 to the base 4:. The base 13 is formed with laterally-extending apcrtured lugs 17 through which extend hold-fast devices 18 which constitute an additional securing n'i eans for coupling the base 13 to the base 4; and the said base Patented Aug. 30, 1910.

Q see 13 is furthermore secured to the base 4 by the hold-fastdevice 19 which extends through the said base. The angle-shaped abutment is-arranged at the rear of the seat and opposing said angle-shaped abutment is an automatically adjustable and springcontrolled locking clamp for secin'ing in connection with the angle-shaped abutment, the seat to the bar The locking clamp consists of a plate 20 secured by the hold-fast devices 21 to the base i and provided with longitudinallyextending depending flanges 21. livotally mnpected by the bar 22 to the inner end of the flanges 21 is a clamping plate 23 which when in position is adapted to engage the bar 2 whereby the latter will be secured between the plate 2 and the angle-shaped abutment, the seat will then be connected in position to the bicycle frame. The clamping plate 23 a t its upper end is formed with a pair of outwardly extending lug ll between which extends the inner section 25 of an extensible bolt, said inner section 25 is pivotally connected to the lugs 24 by a pin 26 and the said inner section extends in the outer section 27 of the bolt, the said section 27 being hollow for the reception of the section 25. Surrounding the. sections 25 and ET is an extensible and wntraetible spring 28 having its outer end as at 29 connected to the outer section .27 and its inner end as at 210 connected to the inner section 25. vThe reference character 31 denotes an ope ating lever provided witha handle 32 and furthermore provided with a pair of lugs which are pivotally connected as at 3e to the outer end of. the outer section 27 of the bolt. The lever 31 is pivotally connected to the outer end ofthe flanges 21 by the bolts 35.

It will be assumed that the position of the elements of the seat is that as shown in Fig. 2 and it is desired to couple the seat to the frame, the seat is inverted and. mounted upon the bar 2, with the brackets 7 straddling the steering head 1, the extension 14 of the angle-shaped abutment bearing against the bar 2, the lever 31 is swung inwardly whereby the clamping plate 23 is brought to engagement with the bar 2 and said plate in connection with the extension 14; couples the seat with the frame.

the reason that the sections of the bolt are connected together by the extensible and contractible spring 28 which will readily adjust itself so that the clamping plate 23 can be' shifted inwardly or outwardly, when moved to clamping position, depending upon the diameter ofthe bar 2, that is to say, if the diameter of the bar 2 is smaller than that as shown, the spring will force the plate 23 inwardly. If the bar is of greater diameter, it is evident that the plate 23 will.

be forced outwardly, but the spring in con nection with the lever 31 will maintain the plate 23 in clamping position.

The brackets 7 not only constitute guiding means to properly position the seat but further constituting means to prevent shifting of the forward portion of the seat with respect. to the steering head, the braces 10 prevent the bending of the brackets 7 3 is obvious, when said brackets are in their operative position with respect to the steering head.

'hat I claim is:

1. A childs bicycle seat comprising abase, retaining brackets depending from the seat and adapted to straddle the steering head of a bicycle frame, an abutment depending from said base and adapted to engage the top bar of the bicycle frame, and a spring controlled clamping de\ ice depending from the base and adapted to engage the top bar of the frame whereby said bar is clamped bet ween said device and said abutmentand the base retained in position upon said bar.

L. childs bicycle sea't comprising a base, retaining brackets depending from the seat and adapted to strarhlle the steering head of a bicvcle. frame, an abutment depending 100 from said base and adapted to engage the top bar of the bicycle frame, and an automatically adjustable spring controlled clamping device depending from the base and adapted to engage the top bar of the frame whereby said bar is clamped between said device and said abutment and the base retained in position upon said bar.

3. A childs bicycle seatcomprising a base,

retaining brackets depending from the seat 11v and adapted to straddle the steering head of a bicycle frame, an abutment depending from said base and adapted to engage the top bar of the bicycle frame, a pivoted clamping plate depending from said base 115 and adapted to engage the top bar of the frame and in connection with said abutment connecting the base to said top bar, an extensible bolt pivotally connected to said clamping plate and'to the base and adapted 120 to maintain said plate in clamping position, and a combined locking and releasing lever for said bolt, said lever pivoted to the bolt and with the base.

In testimony whereof I affix my signature 125 in the presence of two witnesses.
